1 / 4 page © 2004 National Semiconductor Corporation www.national.com ADVANCED INFORMATION March 2004 LMX4168 Radio Transceiver for DECT 1.0 General description The LMX4168 is a radio transceiver integrated circuit opti- mized for the Digital Enhanced Cordless Telecommunica- tions (DECT) system. The transceiver, when combined with a power amplifier and a Tx/Rx switch, implements a com- plete DECT radio transceiver compliant with the ETSI CTR6 standard. The LMX4168 interfaces to National Semi- conductor’s SC144XX DECT family of baseband proces- sors. The LMX4168 integrates a complete transmitter, consisting of a phase locked loop, VCO and PA driver. The receiver contains LNA, quadrature downconverter, polyphase fil- ter/combiner, automatic gain control, and demodulator. The LMX4168 operates from a single 2.25–2.75V supply. The LMX4168 is manufactured in National’s 0.25 µm CMOS technology, and is packaged in a 44 pin LLP pack- age 2.0 Features ■ Highly integrated 1.9 GHz low-IF CMOS transceiver ■ Down conversion to half the DECT channel spacing (864 kHz) ■ On-chip channel select filter ■ On-chip Voltage Controlled Oscillator (VCO) ■ On-chip low noise amplifier (LNA) ■ Open-loop modulation ■ On-chip timing control ■ Four digital (5 mA) output ports ■ 0 dBm PA driver output ■ -95 dBm sensitivity ■ 2.5V operation ■ Small 44 pin Leadless Leadframe Package 3.0 Applications ■ (DECT) Digital Enhanced Cordless Telecommunications 4.0 System Diagram TXDATA RX_DATA RSSI DATA CLOCK LE AGC DEMOD. 0° 90° DEMOD.
